Abstract
The invention discloses a friction-driving compacting unit capable of automatically adjusting compacting force and achieving good use effect. The fiction-driving compacting device comprises a compacting mechanism connected with a driving swinging arm, wherein the compacting mechanism comprises an air cylinder consisting of a cylinder body and a piston rod; the end part of the piston rod is connected with the driving swinging arm; the air-feeding cavity of the air cylinder is connected with the output end of a precision pressure-reducing valve; and the input end of the precision pressure-reducing valve is connected with the output end of a filter pressure-reducing valve. Accordingly, the friction-driving compacting unit of the invention is suitable for friction conveyors.
Description
Technical field
The present invention relates to a kind of load transfer device, relate in particular to the driving pinch device on a kind of conveyer that is used to rub.
Background technology
Pinch device in the tradition friction drive device adopts spring device, because the friction travel line is continuous conveying, the pinch device perseveration, will inevitably cause problems such as spring fatigue inefficacy, under the effect of long-term cyclic loading, the workload of spring descends, produce stress relaxation phenomenon, and when the car group moves to ramp or bend, because required propulsive effort changes at any time, and adopt spring device can't realize accurately regulating automatically, thereby phenomenons such as car or car group jam may occur slipping, thereby cause system's operation not steadily or the generation accident.
Summary of the invention
But the technical problem to be solved in the present invention provides a kind of automatically regulating and compresses dynamics, friction-driven pinch device that result of use is good.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention includes and drive the hold-down mechanism that swing arm is connected, described hold-down mechanism comprises cylinder, described cylinder is made up of cylinder body and piston rod, described piston rod end is connected with the driving swing arm, described cylinder gas input cavity is connected with the mouth of accurate reducing valve, and the input end of described accurate reducing valve is connected with the mouth of filtering pressure reducing valve.
Because the hold-down mechanism among the present invention adopts cylinder, and the cylinder gas input cavity is connected with the mouth of accurate reducing valve, not only can keep the constant of cylinder thrust, but and automatically regulating compress dynamics, adapting to the variation of ramp or bend propulsive effort, thereby improve system's operation stability.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and the specific embodiments:
As shown in drawings: the present invention includes and drive the hold-down mechanism that swing arm 1 is connected, hold-down mechanism comprises cylinder, cylinder is made up of cylinder body 2 and piston rod 3, piston rod 3 ends are connected with driving swing arm 1, the cylinder gas input cavity is connected with the mouth of accurate reducing valve 5, and the input end of accurate reducing valve 5 is connected with the mouth of filtering pressure reducing valve 6.
Principle of work of the present invention is: mainly utilize accurate reducing valve delivery pressure to keep constant characteristic, utilize constant air pressure to keep the constant of cylinder thrust.When load during greater than cylinder thrust, piston rod 3 withdrawals, gas in the jar is discharged by the exhausr port of accurate reducing valve 5, but cylinder thrust still remains unchanged; When load reduces, when being lower than cylinder thrust, piston rod 3 rises, and inner pressure of air cylinder reduces, and at this moment, accurate reducing valve 5 is opened rapidly, inflates in cylinder, guarantees the cylinder constant propulsion.The effect of filtering pressure reducing valve 6 is to make inlet pressurized air cleaning, and the preliminarily stabilised gaseous tension.The present invention can according to around operating mode and transmit attribute (delivery speed, ambient temperature and transmit material, period of service etc.) information automatically regulating and compress dynamics.
